Abstract

A combined direct current circuit breaker includes a transfer branch, an energy absorption branch, at least two primary branches and at least two secondary branches; the transfer branch is connected in parallel with the energy absorption branch; the primary branches are in one-to-one correspondence with the second branches; the primary branches are connected with direct current outgoing lines of a direct current busbar in a high-voltage direct current power transmission system; the secondary branches are connected in series with the transfer branches and then connected in parallel with two ends of the primary branches corresponding to the secondary branches.
